LED bulb goes dim

[Donut417]

I have one of those clamp lights with the Goose neck where you can position the light where you need it. One day I catch the bulb going dim. Like very dim. Do LED bulbs go dim when they are ready to go out? I read somewhere this could be a voltage issue, but my main room light that is an LED has no issue and my UPS doesnt indicate any voltage issues. My room and my moms room are on the same electrical circuit, so I dont believe its a voltage issue with the rooms electrical.  So I was thinking maybe the light fixture itself could be going bad.

I mean, well, it's a lightbulb, you cram mains electricity into it and it does one thing.  Is it not doing the one thing correctly?  Then yes, your lightbulb is broken.

Old school light bulbs work or don’t. Plus taping on the light fixture sometimes changes the result. The fact is still producing light is an indication that it could be something else.

If it has alot of individual LED's in it you may have a few that's gone bad for some reason making it dimmer.

In my experience with these they don't seem to last as long as they claim they will, going dim, they'll start flickering at random or even start blinking..... But I've never had one to just not work period, that much is true for now.

You are hunting for zebras where there are only horses.

Your LED lightbulb is broken, buy a new one.

No I’m questioning why it’s dim. Old school light bulbs work or don’t. I do t have experience with LED bulbs failure. So maybe you could just say that they get dimmer as they fail.

The LED bulb contains a range of circuitry inside.  LEDs don't run on AC power, there's a power supply inside converting that to DC for the LEDs.  There's even more hardware inside if the bulb can be dimmed using a PWM dimmer.  More if it's a wifi enabled bulb.  One of the components are failing.  It is a self contained device and you're not going to diagnose it or fix it.  It's a $4 lightbulb, the fix is 'buy a new one'.
